Process_Description:
DRG's are digital copies of 7.5 minute - 1:24,000 topographic maps published by the U.S.Geological Survey. The USGS produces their DRG product by scanning paper copies of the map at 500dpi and then resampling them to 250 dpi.

USGS topographic maps covering Mississippi were published over a number of years, with the most recent original versions and updates ranging from the early 1960's to mid 1990's.  The DRG's are output as geotif image files georeferenced to UTM NAD 83 coordinates.

The MARIS staff has reprojected the DRG tif files into the MSTM projection and then compressed them using MrSID compression software. The files are stored by blocks designated by degrees of latitude and longitude (for example - 3390 identifies maps with a longitude of 33 degree and longitude of 90 degrees, etc.).
